agb(agent-browser)

What This Skill Does

The agb (agent-browser) skill is a powerful automation tool integrated into the OpenClaw AI ecosystem, designed to bridge the gap between AI reasoning and the web. It provides a robust interface to control a Chromium-based browser, enabling the AI to navigate websites, interact with complex UI components, fill out forms, perform data extraction, and capture visual information. By utilizing accessibility trees and interactive element mapping (refs), the skill allows the AI to perceive the web much like a human would, mapping UI elements to temporary identifiers (e.g., @e1) to ensure precise interactions. This capability transforms a standard LLM into a sophisticated browser agent capable of complex task completion.

Installation

To integrate this skill into your OpenClaw environment, execute the following command in your terminal:

clawhub install openclaw/skills/skills/cecwap/agb

This will provision the necessary agent-browser components and the Chromium runtime. Please ensure your environment allows process management to utilize the browser efficiently.

Use Cases

• Web Automation Testing: Automate repetitive end-to-end testing of web applications, including login flows, navigation validation, and form submission checks.
• Automated Research: Automatically visit multiple URLs, extract key data points, and compile findings into a structured report.
• Dynamic Form Completion: Fill out lengthy web forms or surveys that require data mapping from local documents.
• Visual Monitoring: Capture screenshots of specific web elements or full pages for visual regression testing or tracking status changes over time.
• Data Scraping: Interact with modern, JavaScript-heavy websites to collect information that traditional static crawlers cannot access.

Example Prompts

1. "Open https://example.com/login, fill in my username and password from the context, and take a screenshot after logging in."
2. "Go to the company documentation page, find the search bar, type 'API authentication', and list all the links found in the results section."
3. "Navigate to the registration portal, click the sign-up button, and extract the text from the error message that appears if I leave the form empty."

Tips & Limitations

• Session Management: Always use the --session flag for parallel tasks to prevent state contamination.
• DOM Instability: Remember that web pages are dynamic. Always call snapshot -i after any major navigation or action to ensure your @refs are current.
• Resource Management: Chromium is resource-intensive. Be diligent about using the close command and periodically running pkill -f chromium to reclaim system memory and prevent zombie processes.
• Persistence: Use the --profile flag if you need the agent to remain logged in across multiple sessions. Default execution is headless, which is faster but hides the UI; toggle this if you need to debug visual rendering issues.
